i was woundering if anyone has used superduty springs on the 93-97 f350. i dont know if they would even fit and i was just woundering what the different lengths are from bushing to bushing on a superduty spring and a 93-97 spring is. thanks for the help

 

they will not bolt up, you will have to move the rear spring mount back ~3"

i was doing this just yesterday

-cutts-

 

Are you talking front or rear springs? rears will bolt up if you drill out the mounting points on the truck as the SD spring use larger bolts. But I have seen far more SD rear springs broken than OBS springs.

The front as Cutts said isn't a bolt in afair. The OBS springs are shorter on one end than the other and the SD springs are overall longer and with the center pin centered. Most guys do a shackle reverse (move the shackle to the rear of the spring and move the front fixed mount 4-5 inches forward. The SD springs in front with the shackle reversal will result in a great ride. The same as a SD.

 

Well i was talking about front end and its good to know about the rear springs to. i want to lift my truck somemore and i just didnt know if they would fit or not. do you think it is worth just getting custom springs or doing the superduty ones? i am looking at around 14 to 16 inches of lift.

 

Wow thats a bunch of lift. Yes if you are looking for more lift the Reverse shackle can gain you a few inches and if you set it up to accept SD springs then get the rest of your lift from them.

 

Can I use F250 SD springs on my F350 OBS? Im looking to improve my ride and the shackle reversal might just be the ticket...

 

Yes but it will be custom work for mounting the RSK. There are also issues with locating the bumper with off the shelf brackets

well thanks a bunch. i know thats alot of lift but.... so do you think it is worth making the custom bracket for the superduty springs, and you said i would have to move them back three inches also? above you were talking about the differences in the superduty springs and obs springs what are the main differences and would there be any major problems putting them on there? thanks for the help

 

There will be no problems running the Superduty springs front and rear as long in the front you have your brackets correctly located and the axle stays in the right spot.

The main difference in the Superduty springs is that they are 3-5 inch longer (Can't remember exactly) and they are equal length on each end. The OBS springs are shorter in the front than they are in the rear. centered springs ride better. Also rear shackle suspensions ride better. So if you do the SD spring with RSK you will gain lift and ride quality.

 

I bet a write-up with lots of pictures on this upgrade would be of interest to a lot of people, including me.

Has this upgrade been written-up before? I'm not finding anything.

 

thanks alot man! 1997 F350 you said you had free springs?? are they stock or lift springs? thanks
